Just browsing MN and the ad comes up here promotong something for 'Seniors over 50' 
Sorry but since when women in their 50 (or even just 50) were classed as senior citizens, in this day and age? To be fair the photo there was of a woman who looked 80 (and had scary very white teeth) but come on!
Either say 'seniors over 70' or use the word 'mature' if you mean 50 y.o.
